Title: Gel injection adjustable keratoplasty
Inventor: SIMON GABRIEL
IPC: C08G65/32
Filed: 1993-02-18
Abstract: ABSTRACT OF THE DISCLOSURE     The present invention provides a surgical technique and instrument kit that allows for subtle modification of the corneal curvature by interlamellar injection of a synthetic gel at the corneal periphery while sparing the optical zone. The gel viscosity, volume and disposition within the surgical annular track as well as the diameter of the track, width, depth, and location are all parameters in the refractive change obtained. Following ultrasonic pachymetry performed centrally and at a selected wound entrance located about 2.5 to 3.5 mm from the apex, a one millimeter or so wide, about 75-855% corneal thickness depth radial incision is performed with a micrometric diamond knife adjusted to about 86% corneal thickness. Inserted through the partial-depth incision, a corkscrew-like dissector or helicoidal spatula forms a 360° annular track centered about the apex. A transparent gel is manually injected through the incision, filling the annular channel. Using a surgical keratometer mounted to an operation microscope, the final corneal power is adjusted by massaging and removing the gel as necessary during the primary procedure or subsequent procedures, as the GIAK technique is reversible.

Abstract: A memory mapped keyboard controller (108) within a peripheral controller (103) for use in an Industry Standard Architecture (ISA) computer (102) provides a method and apparatus for efficiently monitoring and reading a keyboard switch matrix. In a first mode of operation, the controller (108) activates all the columns and monitors all the rows in the switch matrix to detect when any one or more of the rows becomes active, indicating that at least one key on the keyboard (112) has been pressed. When any row in the matrix is detected as active, then the keyboard controller ( 108) enters a second mode wherein it selectively activates individual columns and monitors the rows in the switch matrix to detect which row and column contain the activated switch. When the switch location is determined, this location is interpreted by the keyboard controller (108) into a scan code for the ISA computer (102).

Abstract: Despite its potency and broad spectrum antibacterial activity, the therapeutic effectiveness of ciprofloxacin is limited in that it has a short elimination half-life and its potency against some bacteria may be compromised by the ability of some intracellular bacteria to reside and multiply within the human host cells where they are protected from the antibiotic.  These problems can be solved by encapsulating the antibiotic within the microscopic lipid vesicles called liposomes, which protect the drug from dilution and elimination from the body. Moreover, the liposome-encapsulated antibiotic is naturally taken up by phagocytic cells which results in the delivery of the drug to intracellular sites of infection.
